Amazon began as an online bookseller in 1995 operating out of Jeff Bezos' garage. It has since expanded globally and diversified its product offerings. Amazon utilizes a massive technology infrastructure running on Linux to power its e-commerce operations. This includes large Oracle databases and HP servers. Amazon aims to be the most customer-centric company by offering tools, marketing, and a sense of community to help people discover and buy products online through its own warehouses and third-party sellers. Over the past two decades, Amazon has launched numerous international and specialty websites while acquiring companies to grow its business and services.
